(?6)(-5?6+2)
I'm not even sure how to start this problem but I've tried
6squared*-5 6squared+2=
-5?4
 
You have a factor with one term and another factor with two terms. Unless the terms can be combined in the two-term factors, ir is quite unlikelt that a single term will be the result of the multiplication.

\(\displaystyle \sqrt{6} \cdot (-5\sqrt{6}+2) = \left(-5(\sqrt{6})^{2}+2\sqrt{6}\right)\)

This should be familiar. You may know it as something like "The Distributive Property of Multiplication over Addition". Maybe something shorter.

Now what?
